Measurement of the response time of ultrafast photoelectric detectors and dispersive broadening effect of connector with picosecond photoconductive sampling techniques

For measured the response time of ultrafast detectors and some material, we have made one picosecond photoconductive sampling system, it consists of a mode-locked dye laser sysnchronously pumped by a mode -locked argon ion laser and a photoconductive switch using the SOS as substrate. This system has demonstrated a temporal reslution. of under 7 ps, offering a sensitivity of l0 uv
